(57) An imaging system lens assembly includes a first lens group and a second lens group. The first lens group includes a first catadioptric lens element and a second catadioptric lens element, the second lens group includes at least one lens element. Each of an object-side surface and an image-side surface of the first catadioptric lens element and the second catadioptric lens element includes a central region and a peripheral region. The peripheral region of the object-side surface of the first catadioptric lens element includes a first refracting surface. The peripheral region of the image-side surface of the second catadioptric lens element includes a first reflecting surface. The central region of the object-side surface of the first catadioptric lens element includes a second reflecting surface. The central region of the image-side surface of the second catadioptric lens element includes a last refracting surface.
